Most people guess wrong on this. Way wrong.
They picture a bag of seeds and a hose. The real number for one acre of open-field tomatoes runs $15,000 to $40,000 before you’ve sold a single tomato. Go greenhouse and that number jumps to $50,000–$150,000 per acre. And that’s before buying the land.
I pulled real farm budgets – not blog guesses – to break down where every dollar goes. Some of it will surprise you. Some of it will make you rethink the whole plan.
1. Land: The Cost Nobody Budgets For
Here’s the trap. Everyone budgets for seeds and fertilizer. Almost nobody budgets for the dirt itself.
Farmland prices swing wildly by state. Iowa cropland can top $20,000 an acre to buy. California irrigated land ranges from $5,000 for pasture to $30,000+ for prime irrigated ground. Tennessee sits in the middle, around $4,200–$6,800.
These numbers track closely with USDA’s annual farmland value survey, which put the 2025 U.S. cropland average at $5,830 per acre – a useful baseline before you check your own state.
Don’t want to buy? Leasing is the real entry point for most new growers. A basic lease can start around $350 per acre per year. Two acres, roughly $700 a year. That’s the access cost. It doesn’t cover grading, fencing, or fixing a bad water table – that’s separate money, and it’s real money.
2. Open-Field vs. Greenhouse: Two Completely Different Games
Old way: stick transplants in open ground, hope the weather cooperates, sell at market price.
New way: build a controlled structure, extend your season, charge a premium – for a much bigger check upfront.
A basic high tunnel runs $3–$5 per square foot. Scale that to a full acre (43,560 sq ft) and you’re at roughly $130,000–$220,000 just for the covered structure. A full commercial greenhouse build, at $15–$35 per square foot, can land anywhere from $650,000 to $1.5 million for one acre.
If you’re weighing whether that investment is worth it, our greenhouse tomato management guide covers the environmental controls that actually justify the higher cost.
Open-field is cheap to start and brutal to control. Greenhouse is expensive to start and gives you the weather back.
3. What Actually Eats Your Budget: A Real Line-Item Budget
Transplants: $693. Fertilizer and lime: ~$400 combined. Herbicides, insecticides, fungicides: ~$800 combined. Plastic mulch with drip irrigation: $756. Stakes and string: ~$375. Crop insurance: $588.
If you’re setting up your own system instead of paying a contractor, our DIY drip irrigation guide breaks down the same components at hobby scale.
Then labor. Planting, staking, stringing, pruning: ~$1,000 combined. Picking alone: $4,200. Packing: $2,154.
Add it up and total variable costs land around $14,000 for one acre – separate from land and separate from equipment you already own.
4. What You Get Back
Same budget, same acre: projected gross receipts of $19,488, based on 42,000 lbs of tomatoes at blended pricing around $0.46/lb.
Run the math. $19,488 in, roughly $14,000 out, leaves about $5,450 before you touch fixed costs like land payments, equipment depreciation, or your own time.
That’s the number that matters. Not the total spend. The margin.
5. Where This Falls Apart
Here’s the part most cost breakdowns skip.
That $5,450 margin assumes a normal year. One hailstorm, one blight outbreak, one bad price week at harvest, and it’s gone. Tomato prices in that same budget swing from $0.44 to $0.48 a pound depending on grade – a market shift of a few cents wipes out the margin fast.
Greenhouse numbers are worse to plan around, not better. A $650,000+ structure needs years of consistent harvests just to break even on the build, and heating costs alone can swing your annual operating budget by thousands depending on the season.
And every number here assumes commercial-scale intent. A backyard or small market-garden setup can start closer to $10,000 total – a fraction of what a commercial acre costs, because labor and insurance mostly disappear.
Where to Start
Don’t price your farm off a blog post. Price it off your own soil, your own local land cost, and your own labor situation – those three variables move the number more than anything else here.
Get the soil tested first. Price your actual local land lease second. Then build the labor and input budget around what’s left.
The dirt costs more than the seeds ever will.
